Error occurs while exporting animation from blender

[MeteorxBG]

So i made myself a walking animation and wanted to export it to roblox but when i hit the export animation button an error pops off.

This is the error message;

if anyone knows what to do i would greatly appreciate the effort.

I suggest you ask it in the Blender Discord channel: Discord
